Nuget configuration seems to be wrong

[jran...@gmail.com]

I'm trying to install Automapper into a new solution and I'm getting errors from Nuget:

NuGet.Protocol.Core.Types.NuGetProtocolException: An error occurred while downloading package 'AutoMapper.5.0.2 : ' from source 'https://www.nuget.org/api/v2/'. ---> NuGet.Protocol.Core.Types.NuGetProtocolException: An error occurred while downloading package 'AutoMapper.5.0.2 : ' from source 'https://www.nuget.org/api/v2/'. ---> System.InvalidOperationException: 'AutoMapper' already has a dependency defined for 'NETStandard.Library'.

   at NuGet.Manifest.ValidateDependencySets(IPackageMetadata metadata)

[Stack trace truncated]

Is there a work-around for this?

It turns out this was due to having an old version of Nuget installed.
